Usage ¶
setHeightFieldData(session: hapi.Session, node_id: int, part_id: int, name: str, values_array: list of float, start: int, length: int) → bool
Set the height field data for a terrain volume with the values from a flattened 2D array of float. hapi.setVolumeInfo should be called first to make sure that the volume and its info are initialized.
session
The session of Houdini you are interacting with. See hapi.Session for more on sessions. Pass None to just use the default in-process session.
node_id
The node id.
part_id
The part id.
name
The name of the volume used for the heightfield. If set to “height” the values will be used for height information, if not, the data will used as a mask.
values_array
Heightfield flattened array. Should be at least the size of
start + length.
start
The start at least 0 and at most
( hapi.VolumeInfo.xLength * hapi.VolumeInfo.yLength ) - length.
length
The length should be at least 1 or at most
( hapi.VolumeInfo.xLength * hapi.VolumeInfo.yLength ) - start.
